Charts

The chart types specified here are supported by IBM® Operations Analytics Log Analysis. The chart specifications are contained in the <HOME>/AppsFrameowrk/chartspecs directory.

Displaying a chart: To display a chart, you execute your Custom Search Dashboard from the Search workspace. If you close a chart portlet, you must run the Custom Search Dashboard again to reopen the chart.

These parameters are defined for all charts:

type: Specify the type of chart required. The value must match the ID of a chart specification that is contained in the <HOME>/AppFramework/chartspecs directory. The supported chart types are outlined in this section.
title: Specify the chart title.
data: Specify the ID for the data element that is represented in the chart. This ID specified must match to the ID provided in the dashboard specifications.
parameters: Fields to be displayed in the chart.

Line chart

The line chart is defined with these limitations:

Chart name: Line Chart
Parameters: xaxis and yaxis

Chart Specification:

				{
					"type": "Line Chart",
						"title": "Line Chart ( 2 parameters )",
						"data": {
							"$ref": "searchResults01"
						},
						"parameters": {
							"xaxis": "timeStamp",
							"yaxis": "throughput"
						}
					}

Aggregation To aggregate the throughput parameter, define the following code:
```
{
    "type": "Line Chart",
    "title": "Line Chart ( 2 parameters )",
    "data": {
        "$ref": "searchResults01",
        "summarizeData": {
            "column": "throughput",
            "function": "sum"
        }
    },
    "parameters": {
        "xaxis": "timeStamp",
        "yaxis": "throughput"
    }
```
The summarizeData key determines whether aggregation is to be performed or not. column is the name of numeric column that uses the LONG or DOUBLE data type to perform aggregation on. sum is the aggregation function to be applied. Supported functions are sum, min, max.

Bar chart

The bar chart is defined with these limitations:

Chart name: Bar Chart1
Parameters: xaxis, yaxis, and categories
Limitations: Only integer values are supported for the yaxis parameter.

Chart Specification:

					{
						"type": "Bar Chart",
						"title": "Bar Chart ( 3 parameters )",
						"data": {
							"$ref": "searchResults01"
						},
						"parameters": {
							"xaxis": "timeStamp",
							"yaxis": "CPU",
							"categories": "hostname"
						}
					}

Point chart

The point chart is defined with these limitations:

Chart name: Point Chart
Parameters: xaxis and yaxis

Chart Specification:

				{

						"title": "Point Chart ( 2 parameters )",
						"data": {
							"$ref": "searchResults01"
						},
						"parameters": {
							"xaxis": "timeStamp",
							"yaxis": "errorCode"
						}
					}

Pie chart

The pie chart is defined with these limitations:

Chart name: Pie Chart

						}
					}

						"data": {
							"$ref": "searchResults02"
						},
						"parameters": {
							"xaxis": "hostname",
							"yaxis": "errorCount",
							"sub-xaxis": "msgClassifier"

					}

Bubble chart

The bubble chart is defined with these limitations:

Chart name: Bubble Chart
Parameters: xaxis, yaxis, and categories

Chart Specification:

						"data": {
							"$ref": "searchResults01"
						},
						"parameters": {
							"xaxis": "timeStamp",
							"yaxis": "CPU",
							"categories": "errorCode"
						}

       "data": {
        "$ref": "searchResults01"
      	 },
         "parameters": {
           "level1": "hostname",
           "level2": "errorCode",
           "level3": "severity",
           "value":"CPU"
         }
        }
